Web & Mobile App Development

Hi there! My name is Tony Collen, and I'm a freelance web developer based out of Minneapolis/Saint Paul. I'm a full-stack developer, which means I'm comfortable working from the frontend, (slinging HTML, CSS and Javascript), all the way to the backend (managing databases, integrating with third-party APIs, deploying apps, managing servers).

How I Can Help

Custom App Development

I've been building the web for over a decade. Whether it's a more "traditional" webapp, or you're looking for something a bit more mobile, I can help transform your idea for an app into reality.
